Although I personally haven't had time yet to try this asymmetrical layout, I really do like the idea.
UFO doesn't really give the best of examples for his projects though - for example, the large motor that is powered 'by a little battery', has many problems. The lipo battery is a 3S 1350mAh, that's 11.1V. Such batteries have a very linear discharge and can supply up to 30A for 2 minutes, 15A for 6 or 7 minutes, (in the case of the Rhino 1350 and similar).
In short, that battery is hardly little, maybe in physical size, but not in output power. I would expect (from R/C aircraft projects of 5 years) that the battery would power that motor, shown with no load, for many minutes. In fact, the generator output that was shown, did drop as time went along, in keeping with the discharge rate of such a lipo.
His concept videos are excellent, opening the eyes of many to the possibilities of asymmetrical systems. Just wish his videos showed all of his excellent way of thinking.
An example 3S 1350mAh lipo :

The generator output comes from the dual commutator. You can have 2 inputs on 2 connections, 2 outputs on the other 2.
Bare in mind, esteemed fellows such as Tesla have had Patents on very similar ideas and so it's likely to be able to offer unfathomable but real applications.
In a reply from Lidmotor where I suggested an inverter or similar from his motor, he's wanting to try a Tesla tower exciter circuit. That could be very interesting indeed
Can that output run in to a cap and AV plug setup to feed back in to the motor ? dunno yet. Would be fun to find out !
